Abstract

Filter assemblies and fluid flow inhibiters that are particularly well suited for use in centrifugal separation enhanced filtration devices are described. Moreover extensible filter assemblies are described. In one aspect of the invention, extensible filtration assemblies can be used to operate in circulating fluid filtration devices. Such extensible filter elements can use fluid manifold to reduce the effects of fluid circulation inside filter elements and to reduce reverse flow problems in such filters. Additionally, indexable filter elements and invertable filtration elements can be used to extend filter life in filtration in filtration devices.
